The COSMOS build is based on Eclipse PDE (Plug-in Development Environment). The Plug-in Development Environment (PDE) provides tools to create, develop, test, debug, build and deploy Eclipse plug-ins, fragments, features, update sites and RCP products. PDE is built atop the Platform and JDT, and ships as part of the Eclipse SDK. The goal of PDE Build is to facilitate the automation of plug-in build processes [3][4][5] . Essentially, PDE Build produces Ant scripts based on development-time information provided by, for example, the plugin.xml and build.properties files. The generated Ant scripts, can fetch the relevant projects from a CVS repository, build jars, Javadoc, source zips, put everything together in a format ready to ship and send it out to a remote location (e.g., a local network or a downloads server It runs in the eclipse server.

Build Overview

The COSMOS build is based on Eclipse PDE (Plug-in Development Environment). The Plug-in Development Environment (PDE) provides tools to create, develop, test, debug, build and deploy Eclipse plug-ins, fragments, features, update sites and RCP products. PDE is built atop the Platform and JDT, and ships as part of the Eclipse SDK. The goal of PDE Build is to facilitate the automation of plug-in build processes [3][4][5] . Essentially, PDE Build produces Ant scripts based on development-time information provided by, for example, the plugin.xml and build.properties files. The generated Ant scripts, can fetch the relevant projects from a CVS repository, build jars, Javadoc, source zips, put everything together in a format ready to ship and send it out to a remote location (e.g., a local network or a downloads server It runs in the eclipse server.

An automated nightly build runs everyday, the build can also be manually started. The COSMOS build status (Failed/Completed/Progress), build logs, build downloads, dependencies etc can be accessed through a web based dashboard. The builds dashboard is available at http://build.eclipse.org/technology/cosmos/downloads/builds.php

2a) Build Environment
COSMOS build is performed on the eclipse server. The build initially fetch the build module from CVS to the workspace directory. The fetched build module contains various Bash/Ant scripts to perform the complete build. These Bash/Ant scripts broadly perform following functions:

1. SML validator and SML-IF Editor (Resource Modeling)
This package consists of an SML validator that validates SML and SML-IF files, an editor to create and validate SML-IF documents used to exchange information between systems management applications, and tools for importing and exporting SML data to and from a flat file repository.

3. Data Reporting Web Application
This is a web application. It bundles the COSMOS Report Viewer and the COSMOS UI.

Build Process

Build starts automatically and the manual build has to be initiated by a person. If a build is in progress, another build cannot be started. A ".busy" file is created when the build starts and is removed automatically once it is over. The build output contains the deliverables, log files and reports.

The Release Engineering Team will be responsible for running the builds and tests to completion. In the event of problems with the build & test system, they are expected to be resolved as soon as possible and get the build and test restarted. In the event of problems with the build caused by developer checkins it is followed up with developers to ensure fixes are made quickly, and then the build and test are restarted. Any build failure will be reported through bugzilla to the build component for tracking the actual issue as well as trend analysis, etc. All committers are responsible for clean builds and tests. Anytime a check-in is made, the respective person is responsible for monitoring the builds and tests until they pass.

At the end of a successful build, the build output is published to the eclipse server as development build, as part of the build process.

Once the build progress through the different phases, it evolves into stable or release builds. Build type can be changed by editing the file "www/cosmos/downloads/publish_1.0.0.txt" in eclipse repository "dev.eclipse.org:/cvsroot/org.eclipse". In the publish file "publish_1.0.0.txt", build type is displayed as {development/candidate/stable}|{build id}|{comments}, for example stable|COSMOS-1.0.0-200708171630|i5 stable build (Release 0.5)

3a) Build Schedule
3a.1) Daily Builds
An automated build runs every 24 hours. The state of the head branch of the CVS repository will be labeled with a time stamp.
The time stamp will be encoded with the release number, date, time, and serial build number, eg: COSMOS-RMm-YYMMDDHHMMSS.
A module list will be maintained (in CVS) that lists all the modules that are part of the current build, labeling and extracting will be restricted to those modules.

3a.2) Manual Builds
Apart from the daily automated builds, a manual build can be started by those who are authorized to do so.
Starting the manual build on eclipse server:
- Login to eclipse build server (build.eclipse.org) console
- build directory on eclipse server is located at "/shared/technology/cosmos"
- build is started by executing the ./startbuild.sh in "/shared/technology/cosmos/bin" directory

Currently the dashboard doesn't provide any option to start a manual build. This might be added later.

3b) Build Types

Following are various build types

3b.1) Development Builds
All successful daily builds are published to the eclipse server as development builds. Development builds are produced from whatever has been released into the HEAD stream of the CVS repository. They are completely untested and may contain major problems. These drops are normally only useful to developers actually working on this project.

3b.2) Candidate Builds
Selected daily builds are promoted as candidate builds for testing, based on the iteration schedule. They can be promoted to either milestone or release builds.

3b.3) Stable Builds
Candidate builds which pass all the test phases & bugs fixed are flagged as stable builds. Stable builds are tested drivers delivered at the end of each iteration of the development cycle. The latest stable build is the correct build for people who want to stay up to date with what is going on in the latest development stream, and don't mind putting up with a few problems in order to get the latest greatest features and bug fixes. Stable builds are also known as milestone builds

3b.4) Release Builds
According to the release schedule the stable builds are released to the community. Releases are the right builds for people who want to be on a stable, tested release.

Note: Tagged vs Untagged Builds
When a build is tagged, the artifacts used in build are tagged in CVS using the build ID. This is for easily reproducing the build if needed. All nightly builds are tagged builds. Manual builds can be run either as tagged or untagged.

Adding a new dependency or modifying an existing one is done by changing the following files:
a) build.properties - in dev.eclipse.org:/cvsroot/technology/org.eclipse.cosmos/releng/org.eclipse.cosmos.releng.builder/runtime
b) customTargets.xml - in dev.eclipse.org:/cvsroot/technology/org.eclipse.cosmos/releng/org.eclipse.cosmos.releng.builder/runtime

2) dev.eclipse.org:/cvsroot/technology - org.eclipse.cosmos (build artifacts & rel engg)
The build scripts, are located here and can be modified to reflect the change in builds. To setup build you should get the latest files from here. The entry point for build is make.sh.

Porting Build

The release engineering team has completed the process of transferring COSMOS build environment to the eclipse server.
The build directory on eclipse server is located at "/shared/technology/cosmos".

At above location, there are following directories:
1) downloads (on build completion, folder named COSMOS-$Buildld is created and drivers, console/CVS change logs are saved in this folder)
2) workspace (various plugin/features are first fetched to this workspace directory, which are then compiled and packaged)
3) bin (contain various shell scripts used in build)
4) config (contain local configuration files, which specify the build parameters local to build)
5) dependencies (contain various dependencies, based on which the build is constructed)
6) logs (contain logs, used for debugging the build)

The build is started by executing the ./startbuild.sh in bin directory. A cronjob is set on eclipse server to start the nightly builds.

Steps to make build portable on another machine:
1) Make the directory structure similar to what described above
2) Copy all the required files in directories
3) Set parameters in /config/local-build-config.sf file, tuned to local environment setting. For example set the correct JAVA_HOME, ECLIPSE_BUILDER etc

Additional required steps are:
1) comment out the J2SE-1.4 and J2SE-1.5 at the org.eclipse.cosmos.releng.builder/runtime/build.properties and uncomment the J2SE-1.4 and J2SE-1.5, which points to /shared/common/..
2) comment out the cvsloc=cosmos:/cvsroot/technology and uncomment cvsloc=:pserver:anonymous@dev.eclipse.org:/cvsroot/technology org.eclipse.cosmos.releng.builder/make.sh

Access to Eclipse Server
Only authorized users have access to eclipse server. To make password-less connection to eclipse server, such that server do not prompt for password, the eclipse server should be configured to trust the local machine. Here are the steps to make that happen:

1) change directory to .ssh on the local machine (cd /.ssh). In the .ssh directory there are various files such as authorized keys, config id_rsa id_rsa.pub and known_hosts
2) Run the command "ssh-keygen -t rsa" to create the RSA key pair
3) On RSA key pair being generated, run the command "cat id_rsa.pub" and then copy the key
4) cd to .ssh directory on eclipse server and copy this key (from step (3) ) to the file "authorized keys"

Step to create an alias name to connect the eclipse server:
1) cd .ssh directory on the local machine and open config file (less config)
2) Specify the parameters. Host (specify the alias name here) User (specify user name here) HostName: build.eclipse.org

Connecting CVS with SSH
The build machine includes an SSH client for accessing the CVS server. Different methods can be used to authenticate, depending on the level of functionality and security. Authentication methods used by the client by default are, in the following order: public-key, Keyboard-Interactive, and password authentication.

Public-key authentication allows the client to connect to a remote CVS server without sending the password. This is a more secure authentication method than password authentication. Public-key authentication uses two keys, a private key that it should be kept in a secure place and protected with a password. And the public key, is placed on the server (CVS), one wish to gain access to.

Moving build to a different server

The objective here is to create a fully working COSMOS build
on a machine which replicates the build on the IBM eclipse server.

Requirements

Red Hat Enterprise Linux release 4 is used on the Eclipse
server, but you can use Centos Linux 4.6 as it is functionally equivalent to
RHEL 4 and its free whereas RHEL is not.

Access to a local CVS repository containing a replica of the the Cosmos CVS repository org.eclipse.cosmos

IBM Java 1.5. This also needs to eventually work with the
Sun JDK 1.5. (TBD)

Download eclipse-SDK-3.3.2-linux-gtk.tar.gz

Download muse-2.2.0-bin.zip

(Optional) A local Apache Server or any locally accessible
web server. The purpose of this is to have the build dependencies accessible
locally. This is not essential and is only necessary if you have difficulty
bypassing a firewall do retrieve the dependencies during the build process. This
will reduce the download time during the build process.

2)Log
in to root and create the required folder structure with following commands:

mkdir -p
/shared/technology/cosmos/

mkdir
/shared/technology/cosmos/bin

mkdir
/shared/technology/cosmos/config

mkdir
/shared/technology/cosmos/downloads

mkdir
/shared/technology/cosmos/tmp

mkdir
/shared/technology/cosmos/logs

mkdir
/shared/technology/cosmos/workspace

mkdir
/shared/technology/cosmos/dependencies

3)Unpack
Eclipse 3.3 into /shared/technology/cosmos/

Eg.

cd /shared/technology/cosmos/

tar xvfz <download
location>\eclipse-SDK-3.3.2-linux-gtk.tar.gz

4)Install
the IBM Java and record where it is installed. There are many ways to do this.
The version I have was packaged in an RPM and its default install location is /opt/ibm/java2-i386-50.

Build dependencies

Download muse-2..2.0.bin.zip from <a
href="http://ws.apache.org/muse/">http://ws.apache.org/muse/</a>. This file has
an improper "org.apache.wsdl4j" Manifest file, so you need to unzip
its contents and replace file muse-2.2.0-bin\lib\eclipse-osgi\org.apache.wsdl4j_1.6.1\META-INF\MANIFEST.MF
with the fixed manifest.

Once done zip up the contents with exactly the same name and
copy it to the /shared/technology/cosmos/dependencies folder.

The build depends on some third party software, which it
downloads during the build process if necessary. If you are behind a firewall
it the scripts may not be able to connect externally to download these
dependencies so the easiest solution is to download them and store them
separately on a local web server and then configure the build to access that
server .

If you are able to access the dependencies without proxy or firewall configuration, skip to the Build Configuration step.

Install and start a default Apache server instance from the Linux distribution.

The location of these dependencies is specified in build.properties,
which is explained in the following Build Configuration section.

Build Configuration

The build relies on customisations in property files, map
files and the scripts. Before the build can be started some changes have to be
made to the CVS repository where all the build scripts are located.

Make sure you know the connection method and a username and
password to connect to CVS. A cvs connection string is used in many places so I
will define it here as follows:

If you are using Sun JDK 1.5, the J2SE-1.5 entry will be
different to that above. That entry has not been defined yet and will appear
here when known.

Each dependency’s location is stored in this file. If you
are using a local web server to store the dependencies then you should change
the entries for eclipseSdkUrl, birtURL, orbitUrl, WTPUrl, EMFUrl, gefUrl and
equinoxUrl to your local web instance, in my case this is <a
href="http://localhost">http://localhost</a>.

runtime/customTargets.xml

It is only necessary to change this file if you cannot
download through a firewall.

Change the second parameter on each line to your connection
string defined earlier.

maps/dc.map

Each line in this file is comma delimited list of
parameters.

Change the second parameter on each line to your connection
string defined earlier.

maps/dr.map

Each line in this file is comma delimited list of
parameters.

Change the second parameter on each line to your connection
string defined earlier.

Performing Build

When all the above steps are complete, make sure all changes are commited to CVS. Copy all scripts from
the bin_scripts folder in the releng/org.eclipse.cosmos.releng.builder
project into /shared/technology/cosmos/bin folder.

Place the bash/local-build-config.sf in the /shared/technology/cosmos/config
folder

To perform build:

cd /shared/technology/cosmos/bin

./start-build.sh

Results and monitoring

The build can take a few minutes to complete.

On completion a mail is sent to the address specified in the
start-build.sh script, indicating success or failure.

All the build objects are placed in folders /shared/technology/cosmos/downloads/COSMOS/1.0.0/COSMOS-1.0.0-YYYYMMDDhhmm.
Where YYYYMMDDhhmm represents the start date and time of the process.

The log file console.txt is created in /shared/technology/cosmos/downloads/COSMOS/1.0.0/COSMOS-1.0.0-YYYYMMDDhhmm
on completion.

Tagging the Builds

Tagging PDE-Based Builds

It is assumed that a tagged COSMOS build has been performed and that it will be the root of the new tag. Here are the following steps to perform tagging

1) First checkout the map files that corresponds to the build that the tag should be created.
cvs -d cosmos:/cvsroot/technology ex -r <tagname> org.eclipse.cosmos/releng/org.eclipse.cosmos.releng.builder/maps
In COSMOS 1.0.0 i8 driver, there are three map files. Tagging need to be done with all three map files. Also replace <tagname> with tag (for example v1_0_0_i9).
